STEM-WINDING WATCH- Specification of Letters Patent.

Patented June 19, 1906.

Application filed September 16, 1904:. Serial No. 224,704.

To all whom it may concern:

Be it known that I, NUMA BEGUELIN, a citizen of the Confederation of swltzerland,

residing at Solothurn, in Switzerland, have' mechanism for winding a watch and setting the hands by a single winder by means of a two-armed lever or yoke carrying two pinions constantly engaging with a central wheel and of which one can engage with the minute-wheel gear and the other with the wheel of the winding-barrel, according to the position of the said yoke. In this mechanism the two-armed lever or yoke is sub jected to the action of two opposing springs, one having the tendency of bringing it into the winding position and the other, a stronger one than the first, to bring into position for setting the hands.

A construction of the mechanism according to this invention is illustrated,by way of example, in the accompanying drawmgs, in which-- Figure 1 shows the position of the parts for setting the hands; ig'. 2, a view of the parts in position for winding the watch, Fig. 3, a partial under side of Fig. 2, and Flgs. 4 and 5 details.

In Fig. 1 the yoke or two-armed lever C is pivoted at O and carries the two pimons E E, and the pinion E can engage with the Wheel E for setting the hands, and the pinion E can engage with the wheel P of the winding-barrel, Fig. 2. The lever C, Fig. 1, is in the position for setting the hands and is held in that position by a pin H on a lever H, a strong sp'ring G pressing against a second pin H on the lever H, pivoted at H Fig. 3, thus pushing the lever C in the direction of the arrow.

Fig. 2 is a view with the parts in position for winding, the lever C being turned in the other direction, so that the wheels E and P are in gear. For turning the lever for this purpose the pendent stem A, carrying the winding-knob A has a stem F, the squared portion of which passes through a s 3uare opening in the core of the pinion B an the lower end of which stem F bears upon one end of the lever H, pivoted at H By pressing the stem F inwardly against the stress of spring G the lever O is consequently turned in the direction of the arrow, Fig. 3, and the pins H and H thereon are moved to the outer ends of their guiding-slots M in the supporting-plate M-L. e. into the position shown in Fig. 2. This movement removes the pin II from contact with the plate C at C and allows the spring J to force the lower end of the plate C outward into the position shown in Fig. 2, whereupon the pinion E comes into engagement with the wheel P of the barrel for winding the watch.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A winding and hand-setting mechanism for watches comprising a longitudinallymovable operating-stem, a pinion rotatable by the said stem, a series of gear-wheels driven by the said pinion, a pivoted lever carrying said "ear-wheels, spring-winding mechanism and hand-setting mechanism adapted to be engaged respectively by said gearing in accordance with the position of the said lever, a second pivoted lever actuated by said operating-stem, two projections on said lever, one of which is adapted to engage the side of the first lever, a spring acting upon the other projection and a second spring acting in the opposite direction against the side of the said first lever: substantially as set forth.

2. In winding and hand-setting mechanism for watches a longitudinally-movable operating-stem, a sleeve therefor, a pinion fast on said sleeve, a yoke, three gear-wheels on said yoke, the central one of which is in constant engagement with the said pinion and with the two outer gear-wheels, in combination with a pivoted plate II, two projections thereon, two pins thereon adapted to effect the pivotal movement of the yoke and the two springs G and J arranged substantially as and for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

NUMA BEGUELIN.
